Patent EP-0343393-A3 (EP)
Title: Multiscreen pressure diffuser
IPC: D21C9/04
Filed: 1989-04-26
Abstract: A pressure diffuser (10) for paper pulp includes 
a vertical pressurizable liquid-tight vessel (11) 
having a pulp inlet (12) at the bottom and a pulp 
outlet (13) at the top. One or more ring shaped 
screen elements (15), providing first and second 
concentric screen surfaces (16), are vertically 
mounted within the vessel. A number of radially 
extending header arms (18) mount the screen elements 
for movement in the vessel and in fluid communication 
with it. A first linear actuator (37) effects 
reciprocation of the arms. A cylinder (35), open at 
both ends, is affixed to the arms and extends both 
above and below them, and a piston (39) is disposed 
within the cylinder, below the arms. A second linear 
actuator (40) is operatively connected to the piston 
to effect reciprocation of the piston in the 
cylinder. A guiding conduit (46) surrounds the open 
end of the cylinder above the arms and guides 
reciprocation of the cylinder and transports liquid 
from the arms to an effluent outlet. A perforated 
jacket (57) surrounding the guiding conduit, nozzles 
(61) at the vessel wall, and the like introduce 
liquid into the vessel for treatment of the pulp. 
The ring shaped screen element is connected to the 
arms in a manner to allow the best liquid 
communication between them. In this way pulp can be 
effectively treated in a pressurized vessel while the 
screens for treating the pulp are periodically 
backflushed without causing a surge within the vessel.

Title: Procedure and equipment for differentiated juice defecation in two resin packed ion exchange columns
IPC: C13B20/14
Filed: 1989-07-03
Abstract: The process and the related equipment are based on two resin 
packed ion exchange columns (4, 10) through which the juice 
(S) to be defecated is flowing.  
     In the first column (4) the juice is partially defecated through 
ion exclusion thus producing molasses (M) with a satisfactory com­
mercial value, while the defecation process is completed in the 
second column (10) with separation of the non-sugar residue and 
recovery of various sugars and non-sugars having a high market 
value.  
     Treatment on two columns reduces processing time and/or the quantity 
of resin necessary as compared with one column processes. 
Polluting waste water is thus completely eliminated.

Filed: 1989-09-15
Abstract: A shim set for passively shimming (3,2) and (3,-2) 
harmonic terms in the field of the magnetic resonance magnet 
having a cylindrical bore, is provided. Four shims of 
ferromagnetic material, all of the same size, are secured to

centerline of the cylindrical bore and an imaginary line 
extending through the center of the cylindrical bore and the 
center of the shim, at about 30-44° with 38° being the most 
desirable location. The second two of the four shims are 
positioned symmetrically about the axial midplane of the 
cylindrical bore from the first two of the four shims and 
rotated 90° circumferentially relative to the first two 
shims.

Title: Integrated circuit
IPC: H03K19/177
Filed: 1989-06-06
Abstract: A PLL is integrated on the same chip as a 
programmable logic circuit and interconnected therewith 
in any of several useful ways. In one aspect of the 
invention, the output frequency of the PLL may be 
connected to the clock input of registers in the 
programmable logic circuit. If the PLL performs 
frequency multiplication, the chip then becomes a high-­
speed state machine synchronized to a lower-frequency 
input clock. In another aspect of the invention, the 
signal present at different parts of the phase lock 
loop may be provided to inputs of the programmable 
logic circuit. In another aspect, outputs of the 
programmable logic circuit may be used to control the 
operation and/or characteristics of various components 
in the PLL. For example, if a counter is included in 
the phase lock loop for causing the loop to generate a 
frequency multiple of the input signal, the counter may 
be made programmable according to outputs of the state 
machine. Similarly, the characteristics of the phase 
detector or loop filter may be dynamically adjusted 
according to outputs of the state machine. In yet 
another aspect of the invention, an output of the 
programmable logic circuit is, or is used to generate, 
one of the inputs to the phase detector in the PLL.

Title: Method and apparatus for speech recognition
IPC: G10L15/28
Filed: 1990-01-23
Abstract: Speech recognition is performed by using recognizing 
methods suitable for each phoneme after phonemes are 
classified by rough segmentation. Furthermore, matching of 
the symbol series developed from the word dictionary with 
the input speech is performed by means of dynamic 
programming using the table of phoneme recognition results 
obtained in advance by calculation in order to obtain the 
boundary of phoneme in detail. Finally, the recognized word 
is determined by comparing the largeness of the scores 
obtained by this dynamic programming.  
     The improvement in accuracy of word recognition is 
provided by dealing with the difficulty in recognizing 
phonemes by using different recognizing methods by different 
phonemes and the difficulty in segmentation by using dynamic 
programming.
